Ohio, a corporation of Maryland Application December 18, 1934, Serial No. 758,069 In Germany December 20, 1933 11 Claims.

This invention relates to cash registers, accounting machines and the like, and is more particularly directed to machines provided with a multiple item totalizer, from which multiple item totals can be taken, and a plurality of special totalizers. from which subtotals and grand totals can be taken.

The main object of the invention is to classify the entries according to transactions, class of goods, clerks, accounts and the like, and more particularly the multiple-item-totals in multipleitem transactions.

Another object of the invention is to provide means for transferring the multiple-item-total from the multiple item totalizer to one or several totalizers.

Another object of the invention is to simplify the selection and control of engagement of the multiple item totalizer and the special totalizers for item entering and total taking.

Another object of the invention is to provide novel means for compelling the operator to take the total in multiple-item transactions after the entry of the last multiple-item,-before any transaction of. another kind can be entered.

Another object of the invention is to provide a novel arrangement of mechanism controlled by setting means adapted to condition the machine for multiple-item entering and for multiple-item.

total taking.

Another object of the invention is to reduce the number of setting means to be operated for the different modes of machine operations.

Another object of the invention is to enable the amount setting means to condition the machine for a certain mode of operations.

Another object of the invention is to enable certain of the machine conditioning means to release the machine for operation.

Further objects of the invention will be pointed out in the following detailed description with reference to the annexed drawings.

In the drawings one embodiment of the invention is shown by way of example (Figs. 1 to 18) in a machine adapted for the transactions cash,

General description In general terms the invention relates to cash registers and accounting machines especially such adapted for registering single-amounts, multiple-item transactions, and the totals thereof. A special feature of. such machines consists in that the multiple-items of a purchase are accumulated on a multiple item totalizer and in order to finish the multiple-item registration, the total of the multiple-items must be taken. Although a single-item purchase can be regarded as a multiple-item registration with only one item, these so-called single amounts are registered without using the multiple-item totalizer. In order to prevent single item transactions from becoming confused with multiple item transactions, a novel means is provided to make it necessary to complete the entry of the multiple item transaction by taking a total thereof, before any other kind of transaction can be started.

In addition to the multiple item totalizer a. grand totalizer may be provided which accumulates the amounts of all the sales transactions and indicates the total turn over of the department in which the machine is installed. The singleitem transactions are entered directly into this grand totalizer. The total of the items of the multiple-itempurchases can be entered in the same way, however, it may be desirable to enter into the grand totalizer only the total of the multiple-items, which can be effected by automatically transferring the multiple-item-total to the grand totalizer when the multiple item totalizer is set to zero. This mechanism is shown in the modified form of the invention (Figs. 19 to 22) In many cases it is desired to subdivide the amounts transferred to the grand totalizer into different groups or classes. This classification is made mainly according to business transactions (cash, charge, paid out and received on account), kinds of goods, or sales persons. Instead of the grand totalizer, or in addition to the grand totalizer, a plurality of special totalizers corresponding to the classification selected, are provided, which special totalizers have accumulated thereon the totals of different registrations, that is, the single-item and multiple-item transactions.

Interlocking means are arranged between the setting means for facilitating the operation of the machine. The special setting means for the multiple-item transactions (such as keys I6 to I8 and I I to I3 respectively), coact with means so that, by depressing them, the mode of operation zeroizing the itemizer is directly determined, and simultaneously the release of the machine is effected, so that for taking a multiple-item-total one single key only has to be depressed.

According to the invention, the mode of operation control device operated in taking a multipleitem total, by a multiple-item total key, is of such a structure that a coupling means connected with the multiple item totalizer, at a multipleitem transaction, is coupled, upon depressing the multiple-item key and a special key, with an engaging means for the adding action, and, when a multiple-item total is to be taken, with an engaging means for the mode of operation zeroizing upon depression of a multiple-item total key. The coupling of the remaining totalizers with the one or the other engaging means for the different modes of operation is prepared by displacing the mode of operation lever and completed by depressing one of the special keys.

, If the special keys serve as release keys, the special key operated at a multiple-item purchase is not to remain depressed during all of the machine operations pertaining to the said purchase,

but has to be released at the end of each amount entered. Since, however, when a multiple-item is to be entered, only sales of the same kind, or by the same clerk, are to be itemized, an interlocking means provided between the special keys, enforces the use of one special totalizer for all entries of one multiple-item transaction when once started, because only one special key is free.

To have the no sale (change giving) keys function also as release keys which effect opening the cash drawer and, as the case may be, the print of 0.00, is of advantage with machines operated by a plurality of clerks. In this case a plurality of no sale keys corresponding in numher to the subdivision of the clerk keys, is provided by means of which the machine can be released for opening the cash drawer. This subdivision as per clerks similar to the one of the multiple-item total keys serves the purpose that each time the drawer is opened, the initial of the respective clerk is printed and can therefore be checked later on.

The two functions, the release of the machine, and the selection of the totalizers, are effected by a spring, and the mechanism for performing these functions is tripped by the respective spe cial key operated, and both are correlated to one another in such a way that the machine is not released when the movement of the totalizer selecting mechanism is hampered in any way.

When taking a multiple-item-total the mode of operation lever commonly provided for total taking, is not moved but remains in normal position (amount entering). The functions indispensable for the operation of total taking (for example, removing the zero stop pawls for the amount differential members) are not dependent on this lever in the present invention. Instead of controlling the removal of the zero stop pawls by the mode of operation lever, the machine normally tends to remove all zero stop pawls, but depression of any amount key disables the mechanism for so doing.

Due to the arrangement of the special keys and total keys to serve as motor release keys too, it is not necessary to provide for a special motor key bank, and since all these keys and the multiple-item key are arranged within one key bank, the length of the machine is reduced to a very handy extent. The various functions (totalizer selection, mode of operation selection, machine release) are effected by a relatively small number of setting means. Thus the numb-er of manipulations required to operate the machine, is reduced as far as possible, whereas by means of the key interlocking means the correct handling of the setting means for the various machine operations is enforced.

Detailed specification The key board (Fig. l) of this machine consists of a plurality of rows of amount keys I0, a bank of special keys I I to I9 and a mode of operation lever 20. The special keys II to I4 are allotted, f. i., to the transactions cash, received on account, paid out and charge", of which keys that numbered II and I2 are coordinated to a common totalizer, whereas the keys I3 and I 4 operate one special totalizer each which upon depressing one of these keys, is selected in a manner to be described later on, and into which the amount set up each time is entered. The key I5 is depressed for entering multiple-items and selects thereat a totalizer (itemizer) in which the contingent items of a multiple-item transaction are itemized (multiple-item-total). In order to take the total from the multiple-item totalizer one of the total taking keys I6, Ill, or I8 is depressed depending on whether a multiple-itemtotal of several cash sales, of several bills paid, or of several sales on charge occurs. Key I9 is a no sale key. The mode of operation lever to be moved into the positions add, read and reset conditions the machine for total taking, so far as this is not done by operating the multiple-item-total keys I6 to I8.

A plurality of key interlockings are provided to the efiect that the correct operation of the machine during the different modes of machine operations is enforced. If a purchase comprises a plurality of items, only items of the same kind can be accumulated to form a multipie-itemtotal, f. i., only cash sales, or only sales on charge, or only bills paid, however, not items of different transactions. There is practically no need for
